Actually, it was abandon years before the subscription model happened in 2014 and was created in the ancient GameMaker 8.1. Redux is using GameMaker Studio 1.4, as I got it on sale and was never interested in GameMaker Studio 2.
Totally agree! Mine and most other's faith in any engine company has been shattered thanks to Unity. So I'll be using and supporting open source engines as much as possible now, which is ultimately a good thing. Thanks for your sacrifice, Unity. 😜
So I'll be sticking with GameMaker Studio 1 for now (as it's an abandon product with no connected services) and only ever use Studio 2 if I want to release on console.
